Notizen: Abstract The γ-radiation following single and double neutron capture in isotopically enriched62Ni was studied at the high flux reactor of the Institut Laue-Langevin, using a pair and Compton suppressed germanium detector. Measurements before and after 170 d of breeding were performed. The γ-ray fluxes through63Ni and64Ni are discussed; several new levels and spin-parity assignments were found. On the basis of the known discrete levels and the low-energy neutron resonances, level density parameters were determined within the Constant Temperature Fermi Gas model. The neutron binding energies were measured asB n (63Ni)=6837.92(18) keV andB n (64Ni)=9657.64(24) keV. The63Ni (n, γ) cross section for reactor neutrons was measured to be σ=20 −2 +5 b.
